synergy
The interaction or cooperation of two or more drugs or agents to produce a combined effect greater than the sum of their separate individual effects.
In pharmacology, synergy specifically means 1 + 1 = 3 or more (supra-additive effect), as opposed to simple addition (1 + 1 = 2).
Word relationships
- synergism: Synergism is an alternative formal noun specifically preferred in biological and pharmacological literature.
- potentiation: Potentiation often means one non-active drug enhances the effect of an active drug, whereas synergy involves both agents mutually enhancing each other.
- antagonism: An interaction where two drugs oppose or diminish each other's effects.
Commonly confused with
- additive effect: An additive effect means the total effect equals the simple sum of individual effects (1+1=2), while synergy yields a outcome greater than the sum (1+1>2).

When not to use
Do not use 'synergy' to describe simple co-existence or simple additive combined weight; it requires a amplified combined effect.
